This very common assumption -- which I used to hold -- has it exactly backwards. Let's assume tall people and short people are equally good at cracking eggs. Mathematically, if 90% of your egg-crackers are short, you've already hired under-performing egg-crackers. You've passed over some really good tall people in favor of the short people you hired. If you want the best egg-crackers, you need to interview a bunch of tall people.
